From about 1940 to about 1975, global temperatures decreased slightly.

"The time series shows the combined global land and marine surface temperature record from 1856 to 2002."

So, yes, there has been a warming trend. What exactly is this thread supposed to prove?

"The time series shows the combined global land and marine surface temperature record from 1856 to 2002."

And the following time series are representative of the change in global temperature record across the last 500 thousand years, note the minor uptick(i.e. 1856 to 2002 identified as "global warming") to a median temperature in an overall downtrend for the last 2400 years,

One's trend all depends on the time frame one wants to use to make a political point with.
